FIGURE 9. — The SF3A1-UBL domain has a positively charged surface that could potentially facilitate interactions with U1-SL4 RNA. (A) Electrostatic potential analysis of the SF3A1-UBL domain surface performed using the available NMR structure (SF3A1 aa 704–789; PDB ID: 1ZKH). General positions and identity of residues that contribute to the positively charged surface (blue) are highlighted. (B) Ribbon diagram of SF3A1-UBL represented in the same orientation as in A. All residues highlighted in the electrostatic surface potential analysis, and tyrosines Y772 and Y773, are shown.
